12 Apache2 With PHP, Ruby, Python

Now we install Apache with PHP (this is PHP 5.1.6):

yum install php php-devel php-gd php-imap php-ldap php-mysql php-odbc php-pear php-xml php-xmlrpc curl curl-devel perl-libwww-perl ImageMagick libxml2 libxml2-devel

Then edit /etc/httpd/conf/httpd.conf:

vi /etc/httpd/conf/httpd.conf

and change DirectoryIndex to

[...]
DirectoryIndex index.html index.htm index.shtml index.cgi index.php index.php3 index.pl
[...]

Now configure your system to start Apache at boot time:

chkconfig --levels 235 httpd on

Start Apache:

/etc/init.d/httpd start

12.1 Disable PHP Globally

(If you do not plan to install ISPConfig on this server, please skip this section!)

In ISPConfig you will configure PHP on a per-website basis, i.e. you can specify which website can run PHP scripts and which one cannot. This can only work if PHP is disabled globally because otherwise all websites would be able to run PHP scripts, no matter what you specify in ISPConfig.

To disable PHP globally, we edit /etc/httpd/conf.d/php.conf and comment out the AddHandler and AddType lines:

vi /etc/httpd/conf.d/php.conf

#
# PHP is an HTML-embedded scripting language which attempts to make it
# easy for developers to write dynamically generated webpages.
#

LoadModule php5_module modules/libphp5.so

#
# Cause the PHP interpreter to handle files with a .php extension.
#
#AddHandler php5-script .php
#AddType text/html .php

#
# Add index.php to the list of files that will be served as directory
# indexes.
#
DirectoryIndex index.php

#
# Uncomment the following line to allow PHP to pretty-print .phps
# files as PHP source code:
#
#AddType application/x-httpd-php-source .phps

Afterwards we restart Apache:

/etc/init.d/httpd restart

12.2 Installing mod_ruby

For CentOS 5.2, there's no mod_ruby package available, so we must compile it ourselves. First we install some prerequisites:

yum install httpd-devel ruby ruby-devel apr-devel

Next we download and install mod_ruby as follows:

cd /tmp
wget http://www.modruby.net/archive/mod_ruby-1.2.6.tar.gz
tar zxvf mod_ruby-1.2.6.tar.gz
cd mod_ruby-1.2.6/
./configure.rb --with-apr-includes=/usr/include/apr-1
make
make install

Finally we must add the mod_ruby module to the Apache configuration, so we create the file /etc/httpd/conf.d/ruby.conf...

vi /etc/httpd/conf.d/ruby.conf

LoadModule ruby_module modules/mod_ruby.so

... and restart Apache:

/etc/init.d/httpd restart

12.3 Installing mod_python

To install mod_python, we simply run...

yum install mod_python

... and restart Apache afterwards:

/etc/init.d/httpd restart

13 ProFTPd

ISPConfig has better support for proftpd than vsftpd, so let's remove vsftpd:

yum remove vsftpd

Because CentOS has no proftpd package, we have to compile Proftpd manually:

cd /tmp/
wget --passive-ftp ftp://ftp.proftpd.org/distrib/source/proftpd-1.3.1.tar.gz
tar xvfz proftpd-1.3.1.tar.gz
cd proftpd-1.3.1/
./configure --sysconfdir=/etc
make
make install
cd ..
rm -fr proftpd-1.3.1*

The proftpd binary gets installed in /usr/local/sbin, but we need it in /usr/sbin, so we create a symlink:

ln -s /usr/local/sbin/proftpd /usr/sbin/proftpd

Now create the init script /etc/init.d/proftpd:

vi /etc/init.d/proftpd

#!/bin/sh
# $Id: proftpd.init,v 1.1 2004/02/26 17:54:30 thias Exp $
#
# proftpd        This shell script takes care of starting and stopping
#                proftpd.
#
# chkconfig: - 80 30

#              simplicity, security, and ease of configuration. \
#              It features a very Apache-like configuration syntax, \
#              and a highly customizable server infrastructure, \

# pidfile: /var/run/proftpd.pid

# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ ${NETWORKING} = "no" ] && exit 0

[ -x /usr/sbin/proftpd ] || exit 0

RETVAL=0

prog="proftpd"

start() {
        echo -n $"Starting $prog: "
        daemon proftpd
        RETVAL=$?
        echo
        [ $RETVAL -eq 0 ] && touch /var/lock/subsys/proftpd
}

stop() {
        echo -n $"Shutting down $prog: "
        killproc proftpd
        RETVAL=$?
        echo
        [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/proftpd
}

# See how we were called.
case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  status)
        status proftpd
        RETVAL=$?
        ;;
  restart)
        stop
        start
        ;;
  condrestart)
        if [ -f /var/lock/subsys/proftpd ]; then
          stop
          start
        fi
        ;;
  reload)
        echo -n $"Re-reading $prog configuration: "
        killproc proftpd -HUP
        RETVAL=$?
        echo
        ;;
  *)
        echo "Usage: $prog {start|stop|restart|reload|condrestart|status}"
        exit 1
esac

exit $RETVAL

Then we make the init script executable:

chmod 755 /etc/init.d/proftpd

Next we open /etc/proftpd.conf and change Group to nobody:

vi /etc/proftpd.conf

[...]
Group                           nobody
[...]

For security reasons you can also add the following lines to /etc/proftpd.conf (thanks to Reinaldo Carvalho; more information can be found here: http://proftpd.org/localsite/Userguide/linked/userguide.html):

vi /etc/proftpd.conf

[...]
DefaultRoot ~
IdentLookups off
ServerIdent on "FTP Server ready."
[...]

To make sure that FTP users can use the chmod command, comment out the <Limit SITE_CHMOD> section:

[...]
# Bar use of SITE CHMOD by default
#<Limit SITE_CHMOD>
#  DenyAll
#</Limit>
[...]

Now we can create the system startup links for Proftpd:

chkconfig --levels 235 proftpd on

And finally we start Proftpd:

/etc/init.d/proftpd start
